Description

This security bulletin contains information about 1 vulnerability.


1) Directory traversal (CVE-ID: CVE-2010-4270)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:A/U:Amber


The vulnerability allows a remote attacker to view contents of arbitrary files on the server.

The vulnerability exists due to insufficient filtration of user-supplied input in "/administrator/components/com_nbill/admin.nbill.php" and "/components/com_nbill/nbill.php" scripts. A remote attacker can send specially crafted HTTP request, containing directory traversal sequences (e.g. “../”) and view contents of arbitrary file on vulnerable server.

Successful exploitation of the vulnerability may allow an attacker to gain unauthorized access to potentially sensitive information.

Note: this vulnerability is being actively exploited against Joomla! installations.
